Re: system is loosing disk space at extraordinary rate

Neil,

SWA is a topic that I keep a fairly good handle on, and I am not aware of
any memory leaks in V4R5.  For that matter, V4R5 was a fairly sleepy
release for SWA.

It is interesting to note that the memory leak, or what every caused the
increased use of disk space occurred at the job level, whereas a SWA caused
memory leak would typically occur at the system level, IMHO.  "Stuff" that
creates memory leaks at the job (as opposed to the system) level typically
gets found relatively early in a release cycle, and V4R5 is too mature for
this to be unknown to IBM at this late date.

You will also note that he attempting to cure the problem by ending all
user jobs, and this fixed nothing.  It was the ending of subsystems, by
going into a "restricted state" that fixed the problem.  He did not
indicate that the IPL fixed the problem.

I am as clueless as you on this one, although I feel that my long time
friend, SWA is innocent until proven guilty.  If the problem continues to
occur, I would try to end that IBM rascal subsystem, QSYSWRK, and see if
that solves it.

Al - in Charlotte - packing to go home as we speak.  Getting close to a few
tornados today made me remember the words, "There's no place like home.
There's no place like home..."  Just trying to find everything.  Now where
did Toto go?????

By any chance had you been running regular backups using save-while-active
?

Hello all,
this is a strange one:
I did a release upgrade on a V4R4 machine (a 720) to V4R5 in november last
year.
We were at about 50% used disk space at that time. PTF package C0198450
was
installed at that date as well, everything went fine.
Since we did not do any further IPLs since then, we someday noticed that
something
is eating up disk space, until we reached 92 % last week.
Searching for the culprit was at no avail, we ended every user jobs, ended
every non-system
job on the system, it eats space on and on. A short calculation led us to
round about
300 MB (!) temporary space which is used up every day since november.
WRKSYSSTS showed 29 GB of temp used space out of 77 GB total, this is 38 %
of the
whole system !
When we scheduled an IPL to get rid of the temporary used space, I did
endsbs *all *immed
at first hand and suddenly all our used disk space was free again ! You
could watch it coming
back available when pressing F5 in wrkssysts display. I never saw this
behaviour on an AS/400
before. IBM support was nearly as helpless as we, we ordered some PTFs
that might help ...

Any hints anybody ?

Have a nice easter weekend,
regards from germany, Philipp Rusch
